Commercial Toggle Switch
The Hubbell CSB320I is a 20 A single-pole 3-way toggle switch rated for 120/277 V AC circuits. Its shatter-resistant nylon housing and corrosion-resistant construction suit commercial and industrial environments where durability matters. The ivory finish matches standard wall plates in office, retail or institutional settings. UL listing confirms compliance with applicable safety standards.
Wiring Flexibility
Back and side wiring options accept conductors from 14 AWG to 10 AWG secured by screw terminals. This range lets electricians use the same device for lighting loads and motor loads up to 1 hp without changing device types. The maintained contact mechanism holds position reliably in multi-location switching layouts. No locking mechanism is present, so the switch operates with a standard toggle action.
Installation Ready
The package contains the switch body only; no wall plate, mounting screws or wire connectors are bundled. Installers must supply a compatible cover plate and appropriate fasteners for the chosen box. Because the device is a single-gang 3-way unit, two switches are required to control one load from two locations. Buyers needing dimming, indicator lights or smart-home integration should select a different model.

Questions about this item
What is the highest current this switch can carry continuously without overheating?
The switch is rated for 20 A at 120/277 V AC, so sustained loads above that level will exceed its thermal limit.
How warm does the toggle get and how much power does it dissipate when left on all day?
The nylon housing is shatter, crack, corrosion and impact resistant, and the device is UL Listed for commercial use, indicating normal temperature rise under rated load.
What wire gauges and connection style must the installer have ready before wiring this switch?
Screw terminals accept 14 AWG to 10 AWG solid or stranded copper via back or side wiring.
